The technique of capturing sound digitally and recombining or atomising it · the cut-up made instant, non-destructive and pitch-free · the method that displaced the razor blade and underlies glitch, microsound and nearly all contemporary electronic production.
Digital sampling is the technique of capturing sound in digital memory and replaying it at any pitch, looped, sliced, reversed and recombined at will. Granular synthesis is its extreme: sound broken into grains of a few milliseconds each and reassembled into clouds and textures that bear no audible relation to the source. Together they are the digital descendants of the tape techniques · what the razor blade and the spliced loop did to magnetic tape, the sampler does in memory, instantly, at any pitch, and without destroying the original.
The technique arrived with the affordable digital sampler in the late 1980s. The Akai S1000 (1988) is the unit the archive files as the one that ended the analogue era for new electronic-music production: a sixteen-bit sampler that made it possible to load sounds from disk, edit them in non-destructive memory and play them back at any pitch, and in doing so quietly displaced the tape-loop and tape-cut-up methods that had been the genre's compositional default. The S1000 made hip-hop, house, drum-and-bass and the whole 1990s electronic-music economy possible, and it changed the genre this archive covers along with everything else.
The displacement is the central fact of the technique's history within the archive. The tape cut-up file notes that digital sampling absorbed the cut-up method into the editing default and retired the razor blade; this file documents the same event from the other side. Everything the physical cut-up did · the juxtaposition, the recombination, the collapse of the line between musical and non-musical sound · the sampler did faster, reversibly, and with a precision the razor blade never had. The cost was the loss of the physical method's specificity, the irreversible edit and the hand on the tape; the gain was a compositional freedom that reshaped the whole field.
Granular synthesis is the technique's most distinctive contribution. By breaking a sound into grains and controlling their density, pitch, position and overlap, the granular method produces textures · clouds, smears, shimmering beds · that no tape technique could make, because they depend on operations at the millisecond scale that only digital processing allows. Granular synthesis is the basis of much F·19 Glitch, microsound and post-digital work, where the grain is the fundamental unit and the texture is built from the bottom up.
Glitch proper turns the technique on itself. Where sampling and granular synthesis use the digital medium to capture and rebuild sound cleanly, glitch takes the medium's own errors · the skip, the buffer underrun, the corrupted file, the failed read · as material, treating the digital fault as the equivalent of the analogue feedback or the razor cut. The error becomes the sound, which is a recognisably industrial move: the genre has always been interested in the noises a system makes when it breaks, and glitch is that interest applied to the digital system.
The technique's position in 2026 is total. Sampling and granular synthesis are the default of nearly all contemporary electronic production, inside the genre this archive covers and far beyond it; the digital-audio workstation has absorbed every tape technique and made the operations of cut-up, loop and grain available to anyone, at no cost beyond the software. The Bureau files the technique not because it is exotic but because it is the present tense of the genre's compositional method · the technique the older tape methods became, and the one against which their physical survival is now defined.
The Bureau holds digital sampling and granular synthesis as the present-tense compositional technique of the genre this archive covers, filed under glitch. The Akai S1000 is the unit that ended the analogue era; the displacement of the tape cut-up is the central event; granular synthesis and glitch sit as the technique's two distinctive contributions. The file documents the cut-up made instant, and the digital system made to break on purpose.
